Abstract: 258,624. Erban, R. Sept. 21, 1925, [Convention date]. Variable-speed friction gearing comprising race rings 1, 2, Fig. 1, and friction rollers 3 journaled so as to have rotary freedom about three axes at right-angles, has guiding means for each roller 3 capable of engaging that part of a roller such as a, c approaching one of the race rings to move the rollers into a new running path to vary the speed ratio. For gearing adapted for one direction of rotation only the guiding means may be segments 6, Fig. 4, carrying a spindle 5 for a spherical ball bearing 14 on which the roller 3 is mounted, edges a<17>, a<18> on the segments engaging an approaching part of the roller when the lever 10 is operated. In a modification for both directions of rotation, the segments 6, Figs. 5 and 6, carry guiding members 11 turnable on a pin 12. Each member 11 has edges c<28>, d<28>, one edge contacting with a receding part of a roller and the other an approaching part according to the direction of rotation.

Abstract: 1,243,855. Ammonium polyphosphate. UGINE KUHLMANN. 7 May, 1969 [9 May, 1968], No. 23371/69. Heading C1A. Ammonium polyphosphate (which is entirely water-soluble and has a degree cf condensation higher than 50%) is made by preheating " wet process" phosphoric acid, the P 2 0 5  titre of which is between 50 and 60%, to a temperature between 80‹ and 110‹ C., ammoniating the preheated acid with gaseous ammonia to a pH between 4 and 6, and reacting the product with 0À1 to 0À5 moles of urea per mole of P 2 0 5  The phosphoric acid is preferably first freed from suspended organic matter; the heat of condensation of the water vapour which escapes during the ammoniation may be used for preheating the phosphoric acid so that the process becomes autothermic. Impurities such as iron and aluminium are solubilized in the form of complexes, the whole of the P 2 O 5  used thus being recovered as soluble polyphosphate.

Title: Improvements in magnetic transducers and matrices thereof
IPC: G11B5/245
Filed: 1957-07-29
Abstract: 807,397. Magnetic recording and reproducing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 29, 1957 [July 31, 1956], No. 23895/57. Class 40 (2). A magnetic transducer head has means for interrupting the magnetic circuit between the signal energizing means and the record. Four embodiments, Figs. 2 to 5, are directed to heads employing perpendicular magnetization, the simplest form of which is a single pole magnet 10, Fig. 2, having an energizing coil 11 and a saturating coil 13 extending through an opening 14 and connected through a switch 15 to a D.C. voltage source +V. When switch 15 is closed the magnet becomes saturated to interrupt the passage of a signal flux to the pole tip 12. Fig. 3 shows a double pronged magnet in which signal windings 18 and 19 connected in opposition produce a null signal at the tip 17a until a saturating current is switched on to render one limb ineffective. Fig. 4 shows a circular magnet 26 having the signal coil 28 wound on a cross-limb 27. As in the embodiment of Fig. 3, no signal is effective at the pole tip 25a, until an out of balance is produced by a saturating current applied at two diagonally opposite points of the magnet. Fig. 5 shows a slotted single-pole magnet having saturating coils wound on the two limbs. Figs. 6, 7 and 8 (Fig. 8, not shown), are directed to embodiments of heads employing longitudinal magnetization. Fig. 7 shows a normal type of head but having a winding 47 passing through holes 46 in the limbs 43. Passing current through coil 47 saturates the limbs 43 and prevents a signal flux passing therethrough. Fig. 6 is a modification having a core with a cross-bar 48 which in the absence of a saturating current through hole 53 shunts the magnetic gap 58. The D.C. voltage source +V is connected through a change-over switch so that when current is interrupted through the cross-bar, current is passed through holes 52 to saturate the main part of the core to reduce further the possibility of signal fluxes passing through the limbs 49, 50. Fig. 8 is in effect the head of Fig. 4, adapted for longitudinal recording. The Specification describes the use of a matrix of such controllable heads where it is desired to selectively render a particular head operative. The heads are arranged in columns and rows, a common signal source being applied by switching to a whole row at a time, and a common control voltage source being applied by similar switching to a whole column, and thus by appropriate setting of the two switches rendering any desired head effective.
